From 223053783b2374fa45f22600a127c9dcb3bf018c Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Mon, 20 Jun 2016 23:04:21 +0200 Subject: [PATCH] mlxsw: spectrum: Add debug prints For debug purposes, it's useful to know the order in which the driver responds to changes in the topology of its upper devices. Add debug prints to signal these events. Signed-off-by: Ido Schimmel Signed-off-by: Jiri Pirko Signed-off-by: David S.
